On a revisit to Reflex Klystron

Reflex Klystron Oscillator has been studied again to explore the effects of considering bunching parameter X greater than one. It is observed that as X exceeds unity, the relation between the departure time and the arrival time of the bunched electrons becomes as multivalued function and the Fourier component of the beam current comprises not only the in phase term but also quadrature terms and the equivalent circuit consists of linear negative conductance as well as a non linear reactive part.
